Abstract

The present invention discloses a digital remote control multichannel TV programme acquisition return apparatus, which belongs to a device for recording the video / audio signals of the cable TV. The radio and TV programme acquisition monitor comprises a radio frequency input interface, an amplifying distributor, a tuner, an acquisition card and a computer, wherein the radio frequency input interface, the amplifying distributor, the tuner and the acquisition card are directly installed in the chassis of the computer; the radio frequency input interface is connected with the amplifying distributor which is respectively connected with the tuner; the tuner is connected with the acquisition card in sequence; the acquisition card and the tuner are respectively connected with the computer; the computer sends out the command to the tuners so that the tuner receives the appointed cable TV channel, the tuner outputs the analogue video / audio signals to the acquisition card, and the acquisition card outputs the digital video / audio signal to the computer to be recorded. In the invention, by utilizing the computer to control record, the video / audio signals of the cable TV can be recorded and stored in real time. The digital remote control multichannel TV programme acquisition return apparatus provided by the present invention can record eight paths of signals at the same time and has the advantages of simple and convenient use, high efficiency, economy and reasonability.

Description

technical field [0001] The invention relates to a device for recording video and audio signals of cable TV, in particular to a radio and TV program collection monitor capable of simultaneously recording video and audio signals of eight cable TV channels so as to analyze these signals afterwards. Background technique [0002] Cable TV has become an indispensable tool in people's lives. Cable TV broadcasts a wide variety of content, sometimes including illegal and unhealthy content, such as advertisements for illegal drugs. In order to strengthen the supervision of cable TV signals, a device for recording and analyzing multiple cable TV signals is needed. There is no such device in China at present. Contents of the invention [0003] The purpose of the present invention is to provide a radio and television program acquisition monitor capable of simultaneously recording a large number of video and audio signals of cable TV in view of the difficulty in supervising a large nu...
